Hisense ACT-18UR3SGB Ceiling Cassette 18000 Btu/h

Product Description

The HISENSE ACT-18UR3SGB is a ceiling cassette indoor unit rated at 18,000 BTU/h, designed for use in ductless mini-split or multi-split HVAC systems. Ceiling cassette units mount flush into a drop ceiling grid and distribute conditioned air in multiple directions through a centrally mounted panel, making them a common choice for commercial spaces, server rooms, open-floor offices, and larger residential zones. This unit serves as the indoor evaporator component of a split system and requires a compatible outdoor condensing unit to operate. Licensed HVAC technicians handle installation and refrigerant connections.

The ACT-18UR3SGB is suited for light commercial and residential applications where a concealed, low-profile air distribution solution is preferred over wall-mounted or floor-standing indoor units. Ceiling cassette configurations are commonly specified for retail spaces, conference rooms, and open-plan residential areas where airflow coverage and aesthetics are both priorities. Consult the system design documentation to confirm that the outdoor unit capacity and refrigerant line set sizing are matched to this 18,000 BTU/h indoor unit.

Key Features

• 18,000 BTU/h cooling capacity suitable for medium-sized zones
• Ceiling cassette form factor mounts flush in standard drop ceiling grids
• Multi-directional airflow distribution from central ceiling position
• Designed as the indoor evaporator half of a split HVAC system
• Low-profile installation keeps mechanical equipment out of the occupied space

Compatibility

Designed as an OEM-style indoor ceiling cassette unit for use with a compatible HISENSE ductless or multi-split outdoor condensing unit rated to match 18,000 BTU/h capacity.

Installation Notes

Installation must be performed by a licensed HVAC technician holding EPA Section 608 certification for refrigerant handling. Power the outdoor unit off and recover or isolate refrigerant before working on the refrigerant circuit. The ceiling structure must be verified to support the weight of the cassette before mounting. Follow local mechanical and electrical codes for line set routing, condensate drain slope, and low-voltage control wiring.
